... Rev 0; 10/05 General Description The MAX2335 RF front-end receiver IC is designed for CDMA and OFDM applications in the 450MHz band. The MAX2335 includes a low-noise amplifier (LNA) with adjustable IIP3 to minimize desensitization due to cross- modulation in the presence of a large interfering signal. The mixer features differential IF outputs and is designed for high linearity and low noise, which is well suited for CDMA and OFDM applications ...

... CDMA/OFDM LNA/Mixer Detailed Description Low-Noise Amplifiers (LNAs) The MAX2335’s LNA gain and linearity characteristics can be adjusted using the MODE[2:0] inputs. See Table 1 for the pin settings for various operating modes. Use high-gain, high-linearity mode (HGHL) when extra-high linearity is required for cross-modula- tion suppression in the presence of strong interfering signals (e ...
